8 check-ins using file Makefile.in version a7b38485
|17:20||Resolve FROM-clause subqueries after query planning instead of before. Greatly reduce the estimated cost of automatic indexes for VIEWs and ephemeral tables since performance problems there cannot be mitigated via a CREATE INDEX. (check-in: a1eaf171 user: drh tags: view-optimization)|
|10:58||Remove some repeated lines of source code. Probably introduced by careless cut'n'pasting. (Closed-Leaf check-in: a34cd71c user: dan tags: vtab-left-join)|
|22:59||Code refactoring to try to shift FROM-clause subquery manifesting until after the query planner runs. Except this does not currently work because the query planner needs an estimated of the number of rows in the manifested table. Work in progress. (check-in: cabf2187 user: drh tags: view-optimization)|
|18:48||If a query contains "FROM t1 LEFT JOIN t2, t3, t4", ensure that tables t3 and t4 are not scanned before t2. The trunk already does this. (check-in: 0d9edfab user: dan tags: vtab-left-join)|
|18:05||Avoid passing constraints that are unusable due to LEFT or CROSS joins to virtual table xBestIndex() methods. (check-in: 80ee56dd user: dan tags: vtab-left-join)|
|17:42||Fix typo in comment. No changes to code. (check-in: e49c2917 user: mistachkin tags: trunk)|
|17:40||Split out some source code into new files: wherecode.c, whereexpr.c, and treeview.c. Other minor refactoring changes. (check-in: 50f33681 user: drh tags: trunk)|
|15:08||Factor out the TreeView parse tree printing module into a separate file. (check-in: c32ce54c user: drh tags: view-optimization)|
